Can anybody help with design a Common Emitter amplifier for the following specifications:

VCC=10V, VC=5V, RL=1kΩ, Zout= 500Ω, Zin=1kΩ, Gain (small signal)= 6.

how do I derive th R1 and R2 (RB)

But first you need to choose Rc resistor based on desired Zout.
Then you pick Ic based on Rc, Vcc and VC. Next you pick Re based on desired Gain.

am studing electronic engineering. We went to practicals and the lecture asked us to design it
unfortunaly am finding it diffcult to upload the circuit networ

Unfortunately am finding it difficult to upload the circuit. However it has no values

The question wasn't the general area you are studying, but rather what you are studying that is directly related to this project.

Have you studied small signal models for the transistors and what the output impedance is using that model?
